Selenium ekudleni

I-Selenium yinto ebalulekileyo yokulandelwa kwezimbiwa. Oku kuthetha ukuba umzimba wakho kufuneka ufumane le minerali ekutyeni okutyayo. Inani elincinci le-selenium lilungele impilo yakho.

I-Selenium yimbumbulu. Umzimba wakho uwufuna kuphela ngexabiso elincinci.

I-Selenium inceda umzimba wakho wenze iiproteni ezikhethekileyo, ezibizwa ngokuba zii-enzyme ze-antioxidant. Oku kudlala indima ekuthinteleni ukonakala kweseli.

Olunye uphando lubonisa ukuba i-selenium inokunceda kwezi zinto zilandelayo:

• Khusela umhlaza othile
• Khusela umzimba kwiziphumo eziyityhefu zesinyithi esinzima kunye nezinye izinto eziyingozi

Izifundo ezingaphezulu ngezibonelelo ze-selenium ziyafuneka. Okwangoku, ukuthatha isongezelelo selenium ukongeza kwimithombo yokutya ye-selenium okwangoku akukhuthazwa kwezi meko.

Ukutya kwezityalo, njengemifuno, zezona ndawo zixhaphakileyo zokutya kwe-selenium. Ubungakanani be-selenium kwimifuno oyityayo kuxhomekeke kubungakanani bezimbiwa ezazisemhlabeni apho kwakhula khona izityalo.

Amantongomane aseBrazil angumthombo olungileyo we-selenium. Iintlanzi, i-shellfish, inyama ebomvu, iinkozo, amaqanda, inkukhu, isibindi kunye negalikhi nayo iyimithombo elungileyo. Iinyama eziveliswe kwizilwanyana ezazisitya iinkozo okanye izityalo ezifumaneka kumhlaba ocebileyo ngeselenium zinamanqanaba aphezulu eselenium.

Igwele leBrewer, intsholongwane yengqolowa, kunye nesonka esityetyisiweyo zizinto ezilungileyo zeSelenium.

Ukungabikho kwe-selenium kunqabile kubantu baseMelika. Nangona kunjalo, ukusilela kunokwenzeka xa umntu esondliwa nge-vein (IV line) ixesha elide.

Isifo seKeshan sibangelwa kukungabikho kwe-selenium. Oku kukhokelela kukungaqheleki kwentliziyo yemisipha. Isifo seKeshan sabangela ukusweleka kwabantwana eTshayina kude kube kufunyanwa ikhonkco kwi-selenium kwaye kwanikwa izongezo.

Ezinye izifo ezibini zidityaniswe nokusilela kwe-selenium:

• Isifo seKashin-Beck, esikhokelela kwisifo esidibeneyo kunye nethambo
• I-Myxedematous endemic cretinism, ekhokelela kukhubazeko ngokwasengqondweni

Iziphazamiso ezinzima zesisu sinokuchaphazela amandla omzimba okufumana i-selenium. Ezi ngxaki zibandakanya isifo seCrohn.

I-selenium eninzi egazini inokubangela imeko ebizwa ngokuba yi-selenosis. I-Selenosis inokubangela ukulahleka kweenwele, iingxaki zesikhonkwane, isicaphucaphu, ukucaphuka, ukudinwa kunye nokonakala kwethambo. Nangona kunjalo, ityhefu ye-selenium inqabile e-United States.

Imilinganiselo ye-selenium, kunye nezinye izondlo, zibonelelwa kwi-Dietary Reference Intakes (i-DRIs) ephuhliswe yiBhodi yokutya kunye neZondlo kwiZiko lezeMpilo. I-DRI lixesha leseti yokubhekisa esetyenziselwa ukucwangcisa nokuvavanya ukungena kwezondlo kwabantu abasempilweni.

Ingakanani ivithamini nganye oyifunayo kuxhomekeke kubudala bakho kunye nesini. Ezinye izinto, ezinjengokukhulelwa kunye nokugula, nazo zibalulekile. Abasetyhini abakhulelweyo okanye abancancisayo badinga imali ephezulu. Buza umboneleli wakho wezempilo ukuba leliphi elona xesha lilungele wena. Ezi xabiso zibandakanya:

• Isibonelelo seDiary esicetyiswayo: Umgangatho wemihla ngemihla wokutya okwaneleyo ukuhlangabezana neemfuno zezondlo phantse zonke (iipesenti ezingama-97 ukuya kuma-98%) zabantu abasempilweni. I-RDA linqanaba lokutya elisekwe kubungqina bophando lwenzululwazi.
• Ukutya okwaneleyo (AI): Eli nqanaba limiselwe xa kungekho bungqina bophando lwenzululwazi baneleyo bokuphuhlisa i-RDA. Ibekwe kwinqanaba ekucingelwa ukuba liqinisekisa ukondla okwaneleyo.

Iintsana (AI)

• Iinyanga ezi-0 ukuya kwezi-6: ii-micrograms ezili-15 ngosuku (mcg / ngosuku)
• Iinyanga ezi-7 ukuya kwezi-12: 20 mcg / ngosuku

Abantwana (RDA)

• Ubudala 1 ukuya ku-3: 20 mcg / ngosuku
• Ubudala 4 ukuya ku-8: 30 mcg / ngosuku
• Ubudala 9 ukuya ku-13: 40 mcg / ngosuku

Ulutsha kunye nabantu abadala (i-RDA)

• Amadoda, aneminyaka eli-14 nangaphezulu: 55 mcg / ngosuku
• Abafazi, abaneminyaka eli-14 nangaphezulu: 55 mcg / ngosuku
• Abafazi abakhulelweyo: 60 mcg / ngosuku
• Lactating fema: 70 mcg / ngosuku

Eyona ndlela yokufumana imfuno yemihla ngemihla yeevithamini eziyimfuneko kukutya ukutya okunesondlo okuqulethe iintlobo ezahlukeneyo zokutya.

• Selenium - antioxidant
